Document Type and Number:
Japanese Patent JP3958436
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a lead-free stabilizer with improved thermal stability and low temperature heat aging resistance for a chlorine-containing polymer and to obtain a lead-free chlorine-containing polymer composition excellent in thermal stability and low temperature heat aging resistance and useful as a wire- covering material.
SOLUTION: There are provided a stabilizer for a chlorine-containing polymer and a resin composition containing the same, the stabilizer comprising(A) a fine crystalline calcium silicate having a chemical composition represented by the formula: CaO.xSiO2.nH2O (wherein (x) is a number not less than 0.5 and (n) is a number not more than 2.5) and X-ray diffraction patterns including spacings at 3.01-3.08 &angst , 2.78-2.82 &angst and 1.81-1.84 &angst , or its complex with a polyhydric alcohol and (B) a cyanurate compound, the components (A) and (B) being contained in a wt. ratio of (A) to (B) of 5.0:95.0 to 99.8:0.2.
